Guizhou railway becomes the "composer" of a new chapter in Guizhou's development

China's first green mountain railway, Chengdu Guiyang high-speed rail, was launched on the 16th. The high-speed railway connecting the three provinces of Sichuan, Yunnan and Guizhou will become a new road to prosperity for local residents. (cctv.com)

Chengdu Guiyang high speed railway starts from Chengdu, Sichuan Province, passes Meishan, Leshan and Yibin, Weixin County, Zhenxiong County, Zhaotong City, Yunnan Province, Bijie City, Guizhou Province, and ends in Guiyang city. Among them, the line from Yibin to Guiyang is 374km long, with 11 stations, including Yibin West, Changning, Xingwen, Weixin, Zhenxiong, Bijie, Dafang, Qianxi, Qingzhen West, Baiyun north and Guiyang North. One is Guiyang, the other is Chengdu. With a total length of 648km, Chengdu Guiyang high-speed railway is open to traffic, which marks that Guizhou has added a fast railway channel out of the province, and five directions of fast railways have been built in Guiyang. Guizhou has become one of the provinces with the widest coverage of fast railways. As a high-speed railway hub in Southwest China and one of the top ten high-speed railway hubs in China, Guiyang has become more consolidated and improved. The construction of

Chengdu Guiyang high speed railway is very difficult, because the terrain along the railway is very complex and dangerous, and the route mostly twists and turns between the Sichuan basin with an altitude of 200 meters and the Yunnan Guizhou Plateau with an altitude of 2000 meters. The proportion of tunnels is nearly 60%, especially in the Yunnan Guizhou section. The construction difficulty is unprecedented. For example, yujingshan tunnel is very rare in the engineering history at home and abroad, known as "the first high-speed railway tunnel" in the industry. After 10 months of program research, 5 expert reviews and hundreds of on-site meetings, our railway workers have completed the solution of yujingshan tunnel karst cave, which has realized that the bridge in yujingshan tunnel has reached the settlement standard and ensured the stability of the bridge in the tunnel. Finally, the arduous task has been completed, making Chengdu Guiyang high-speed railway open to traffic smoothly. With the completion of Chengdu Guiyang high speed railway, the "eight vertical and eight horizontal" high speed railway network from Lanzhou (Xining) to Guangzhou has been successfully completed.

not only that, with the operation of Chengdu Guiyang railway, on the basis of the previous operation of Chongqing Guiyang railway, Guizhou has formed a "ten" shaped high-speed railway network with Guiyang as the center. From Guiyang, you can take the bullet train to Guangzhou to the south, Chongqing and Sichuan to the North, Changsha to Shanghai to the East and Kunming to the West. The three national planned high-speed railway passes through Guiyang, leaving only the high-speed railway from Guiyang to Nanning in the Baohai channel, which will be completed and opened to traffic in 2022. In the future, Guizhou's high-speed rail network will be more intensive, fast and convenient. At the same time, with the gradual completion of the high-speed railway network, the passenger capacity of the existing ordinary speed railway will also be improved, and the freight capacity will be greatly improved. In Guiyang, the port will enter the stage of completion acceptance. Guiyang gaimao railway port is a first-class open port, which will become a station of China Europe train after completion and operation, with an annual freight throughput of 1.2 million tons, and will further promote the docking of Guizhou Province with the "belt and road" and the "new channel of international land and sea trade".

therefore, it is not difficult for us to foresee that with the development of modern comprehensive transportation in Guizhou, people flow, logistics, capital flow and technology flow are gathering here continuously, and the gathering of these "flows" will surely enter a new chapter in the development of Guizhou, and the composer of this chapter is Guizhou railway.
